Suprasteve Posted September 7, 2005 Share Posted September 7, 2005 i've looked a MONKEYmarks drag racing times and noticed the stock turbos range mainly from 12.7 to 13.8 for the 1/4 mile. I'm interested to know of which are BPU? does anyone know an avarage time for a 6sp Jap BPU at Santa Pod on normal weather conditions. I know they're gunna vary greatly with soooo many other things to take into concideration but just after a rough guide. My best so far is 13.4 @106 mph at Santa Pod in April this year. I had at the time 1 cat still in (by the engine) running 1 bar with a crappy very resticting exhaust. I'm now BPU with Blitz Nur Spec etc... running 1.2 bar Standard Eagle F1's 17inch tyres. I would like to think on a good start and gear changes etc i could get late 12s with a top end of may be 110mph. Am I being realistic or am i in dreamland ? Please don't burst my bubble, be gentle.

Soop Dogg Posted September 7, 2005 Share Posted September 7, 2005 Should be do-able with slick changes etc. I did a 12.87 in my auto a couple of years ago with just a double decat and a FCD. Santa Pod doesn't have the best grip in the world though.... Link to comment Share on other sites More sharing options...

Alex Posted September 7, 2005 Share Posted September 7, 2005 Why not plot all the 6speed stock based times on a graph and then you'll see from the trend what the average time is. Link to comment Share on other sites More sharing options...
Suprasteve Posted September 7, 2005 Author Share Posted September 7, 2005 Why not plot all the 6speed stock based times on a graph and then you'll see from the trend what the average time is. I thought of doing that but MONKEYmark hasn't stated what mods they have so sort of guess work really. Just thought that may be a few people on here have done a 1/4 mile with 6sp BPU and could tell me their times so i had an avarage to compare them. The real reason for my original question is that my mate has just had a remap on his EVO6 and is now running 346 fwbhp and getting a twin plate clutch fitted. He's been told from people on the EVO site that he should be getting around the 12.8 @ 106 mph with his mods. It would be nice to know if i could match/beat him or not before i start the friendly banter that mates do before we race. Link to comment Share on other sites More sharing options...
JohnA Posted September 7, 2005 Share Posted September 7, 2005 ...my mate has just had a remap on his EVO6 and is now running 346 fwbhp and getting a twin plate clutch fitted. ... ouch proceed with caution Why don't you try rolling start 'tests', like from 80mph upwards? You'll kick his ass then Link to comment Share on other sites More sharing options...
Suprasteve Posted September 7, 2005 Author Share Posted September 7, 2005 ouch proceed with caution Why don't you try rolling start 'tests', like from 80mph upwards? You'll kick his ass then done that already and yep within a couple of seconds i was 2 car lengths in front and still pulling away. We're going Santa Pod on the 25th Sept, i think he'll be getting his own back :thumbdown Link to comment Share on other sites More sharing options...
colsoop Posted September 7, 2005 Share Posted September 7, 2005 I think your terminal speed is very likely i am bpu and have a best terminal speed of 112 mph, the high 12 second pass is possible but it is going to take practice and a decent grip surface.

MONKEYmark Posted September 7, 2005 Share Posted September 7, 2005 not enough room to put all info about each car on list. if people want to do a picture of all there spec i can put it as a link at the side of there name on list, what is bpu anyway.lots of cars go double de cat and exhaust. if you tried some sticky tyres it helps loads read that drag radials can knock off up to 1/2 second. the manual cars seem to have trouble launching,it can be done just look at the crd launch. some cars have more mods than others.would fitting 550cc injectors be classed as a + on the bpu scale.just look at terminal speeds of the cars see how you compare.or look at detailed drag strip listing, you can see how you doing against another car at different points up the track.

Cheers Mark. I wasn't having a pop at you for not having all the information on the table as this clearly is a massive job and you'll be forever updating it. The inforamtion you have input already is fantastic. I've looked on other websites (non toyota ones) and they don't have such information. Do you think if i asked Aerotop Dave nicely (seeing that he has written a blinding write up on BPU in the Tech section) if he can do another for BPU+, BPU++, hybrid & single (plus the stages along the way) just so we all know exactly what stage of modding we are at and what to do next or just to have some rule or bench mark to base things on !??!

Ian C Posted September 7, 2005 Share Posted September 7, 2005 The modification path isn't exactly linear mate I class BPU as running 1.2bar of boost on stock turbos, with or without FMIC, cams, zorst, etc -Ian Link to comment Share on other sites More sharing options...
MONKEYmark Posted September 7, 2005 Share Posted September 7, 2005 too many configurations really to break it down like that, so many things like different tyres,fuels,drivers who not got experience.different levels of mods. i dont have a boost controller or fuel computers. my car has no boost controller no fuel computer but have tried lots of combinations how to beat times. best time have done on 1bar boost with full weight running some 113 race fuel for peace of mind, dont know if it even takes advantage of it on stock ecu.never reset ecu or took headlight out. on drag radials with cw decats with restrictor ring fitted if i remember.blitz nur spec exhaust, and a wonky fitted blitz fmic.4000tc ,ngk plugs,hks 264 264 cams and gears, and water injection with 70/30 methanol/water mix. and rltc (turned off) what in the bpu does that make me? would love to try a small shot of nos and try now i stripped lots of weight out of car. think you will find the launching is where its at. we all know supra is good when its up and running i keep trying to get intrest and thinking of more ideas to try mahe it better, you dont see many lists like this on other boards. would have thought the gtr would have had one.

hadyn Posted September 7, 2005 Share Posted September 7, 2005 my BPU car with 1 bar boost and smic does 13.5-13.6 all day with no launch And terminals of around 108mph I'd like to think i could dip into the 12s if I actually launched the autobox properly Link to comment Share on other sites More sharing options...

I had a crappy exhaust which i've now fitted a Blitz and running 1.2 bar - feels soooo much more powerful, hence i'm hoping to get into the 12s. happy days Link to comment Share on other sites More sharing options...

hadyn Posted October 9, 2005 Share Posted October 9, 2005 Just thought i'd bump this due to me now at 13.3 with BPU 1bar and the fact that a few of the board should have had somes runs at the pod today? Link to comment Share on other sites More sharing options...
MONKEYmark Posted October 9, 2005 Share Posted October 9, 2005 what was it like today,did weather hold out ok. also any good times want updating let me know. i want to get mine out again now record been broken. start a new thread and get some pics up Link to comment Share on other sites More sharing options...
Bobbeh Posted October 9, 2005 Share Posted October 9, 2005 Hehe Mark, feeling the heat now huh - its good to have the competition.. I remember watching you doing your 11.9, and I though, oh he must have his single fitted now - doh Yeah I hope some nice times were run today, seeing it was pretty much the last decent big meet opportunity to run the 1/4 mile. I had a constructive day spent in bed Link to comment Share on other sites More sharing options...

Jake Posted October 9, 2005 Share Posted October 9, 2005 My BPU¹ 93 RZ Auto gets terminal speeds of 110+mph easily. My best terminal is 116.27mph, best ¼time is a poor 13.340 but I reckon that is mainly because of the slow-to-get-going auto box. With a high-stall TC I would expect to easily get in the twelves and hopefully a bit better terminal speed. ¹(full decat, walbro pump, FCD, stock airbox, E-01 @1.2 bar) Link to comment Share on other sites More sharing options...

Jake Posted October 9, 2005 Share Posted October 9, 2005 dont you lose terminal when you fit a high stall I don't really know. How can a better start give you slower terminal speed? Link to comment Share on other sites More sharing options...
MONKEYmark Posted October 9, 2005 Share Posted October 9, 2005 I don't really know. How can a better start give you slower terminal speed?dont know how it works out.i was on about when you go with higher stall it robs your terminal. Link to comment Share on other sites More sharing options...
hadyn Posted October 9, 2005 Share Posted October 9, 2005 .... best ¼time is a poor 13.340 13.3 is not a poor 1/4 mile time Jake. Im constantly seeing TT's getting mid 14s and even 15s at a lot of RWYB days I go to. Link to comment Share on other sites More sharing options...
